The advisorship can include a free visit of the Observatory, his own participation in a school activity (a talk, a question and answer session, a workshop), or an introduction to celestial observing. In the latter case, the astronomer will bring a small instrument to observe the Sun or the stars at night.

The advisorships are supported by a ministerial presence housed at the Observatory "Science at school". There is also a partnership with Planète-Sciences which adds an instrumental element.
